Abstract (en)
A memory cell of MRAM includes a PMOS transistor and a storage element. A first terminal of the PMOS transistor is connected with a first end of the memory cell. A control terminal of the PMOS transistor is connected with a second end of the memory cell. A first terminal of the storage element is connected with a second terminal of the PMOS transistor. A second terminal of the storage element is connected with a third end of the memory cell. During a write operation, a first voltage is provided to the first end of the memory cell, a second voltage is provided to the third end of the memory cell, and a control voltage is provided to the second end of the memory cell. Consequently, the memory cell is in a first storage state.
